FT-IR sample preparation
Sample/KBr ratio The concentration of the sample in KBr should be in the range of 0.2% to 1%. The pellet is much thicker than a liquid film, hence a lower concentration in the sample is required (Beer's Law). Too high a concentration usually causes difficulties obtaining clear pellets. The IR beam is absorbed completely, or scattered from the

Thermodynamics tells us that: Equilibrium and Metastable States • Under conditions of a constant temperature and pressure and composition, the direction of any spontaneous change is toward a lower free energy. • The state of stable thermodynamic equilibrium is the one with minimum free energy.
